Letters Patent No. 86,027, dated January 19, 1869.

IMPROVED GAS-REGULATOR.

Th Schedule referred to in these Letters Patent and making part of the same.

To all whom may concern .Be it known that I, SAMUEL I. Mnnvnm, Jr., of. the city and county of Philadelphia, in the State of Pennsylvania, have invented an Improved Gas-Regulator: and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawing, through lettors oi reference marked thereon, forming part of this specification, and in which----- Figure 1 represents a central vertical section of an apparatus embracing my improvements, and

Figure 2. a. horizontal section of the same, taken on the line :c x oi fig. 1.

Thesame letters, occurring in both figures, indicate like parts.

The object of my invention is to construct a gasregulator, that shall be more sensitive in its operation,

" air-chamber, in connection with the regulator.

l urthermore, itconsists in a novel construction of the regulating-valve, whereby it becomes selt lubrieating.

The peculiar advantages of these several features will hereinaitcr appear.

To enable others skilled in the art to make and use my invention, I will describe it by referring to the drawing, in which A represents a cylindrical vessel, open at the top, and having a bottom, I), flat, or otherwise suitably formed, to the central portion of which is attached a hollow cone, B, extending upwardly about three-fourths the-depth of the chamber A; and concentric within the cone B is au inverted hollow cone, 0, terminating upwardly at about the same level as the eerie B, and passing through the bottom, I), and bowl-shaped sink A, beneath, with both of which it is rigidly connected in a water or air-tight manner. 1

The upper end of this inverted cone 0 has fitted t it a screw-cap, m, in which is provided a central apex ture, ibrming the seat for the valve F, to be more fully explained hereinafter.

The vessel or chamber A is also provided with an aperture in its side, which is closed with a screw-stopper, K, for regulating the level of; the water or other fluid contained in said vcssehwhich occupiesthe annular space within it and around the conical chimney B.

U represents an inverted conical vessel, open at its lower end, and closed by a contracting and arched cover at its upper end; and around the lower end of which, on its outer periphery, is constructed an air-chamber,

E, formed by soldering two curvilinear plates of metal around its lower portion; and which, whilst it is not of sulficient capacity to float said inverted vessel, gives it buoyancy and renders it more sensitive to the illictuatiug pressure of the gas in its passage t-heretln-ough.

Centrally, at the upper end or cover ol'this res-sol D, is suspended a valve, P, which, as said vessel rises and falls by the arying force or pressure of the gas, opens and closes the aperture in the centre of the cap on. This valve is of novel construction, being of hollow conical form, and having a series of apertures in its sides, with a central discharging-passage in direction of the arrows, as well as an annular passage around it, through the aperture in the cap m, the principal current being through the central or tubular portion of the valve-stem, and the gas, by this tortuous passage, being caused to disengage from and dcposit auy aqueous particle's, carried with it, in the cavity oi the valve, which, accumulating to the level of the lower apertures in the periphery of the hollow stem, will ilow over and lubricate the valve, thus accomplishing the twofold purpose of reducing friction in the operation of the valve, and separating and depositing the aqueous particles in the bowl A, where they may be readily drawn off, and will not cause any flickering of the light at the burners.

The invcrted'vessel I) is furthermore sustained and V guided in its central and vertical position and movement within the vessel A, by three or more guiderollers, a, at or near its upper and lower extrcnntics.

The apparatus, thus constructed, and charged with water or other liquid to the level of the stopper K, is-

attached to the egress-pipe of the meter by means of the coupling L.

The stop-cock? being closed, and those marked I" and 1? opened, the gas will traverse the pipe S, in the direction indicated by the arrows, passipg up the inverted conical chamber 0, through and arouud'thc hollow valve B, into the chamber H, where it impinges on the concave cover or top thereof, and escapes downwardly through the annular passage J, formedbetween the conical chimney B and the inverted cone (Land out through a series of apertures, f, into the bowlshaped bottom A, where any moisture carried over from the meter or re rulator is deposited, to be drawn off occasionally at the plug R. v

The supply-pipe S is also provided, at its lowest point,-with a similar plug, for the removal of any water that may accumulate therein.

From thchamlrbr A, the gas pontinues its course, through the pipe '1, to the burners, in the direction also indicated by arrows.

In case the regulator should get outof order, or, for any reason, it should not be desirable to use it, the gas may-pass direct to the burners through the passage S, by opening the stop-cock P and closing those marked P and P.

By this combination of cones,

enlarging passages through the regulator," it will be seen that the passage of jhe gas can in no degree afforming gradually'- feet its wctionhy friction, or impinging on any of its sides or other parts/but that its action will he eontrolled entirely by the pressure of the volume within the chambeefi aetingto raise the float D, and, at the same timeyite contrast the annular orifice aronndthe valve F, and to reduce the number of apertures, i, in

its hollowst'en' by covering a portion of them up, or raising some otthem above the cap in, when 'theybe some egress instead of ingress-apertures.

It will also be seen that by the angular or conical formation of the air ehamber or float E, and its arrange merit outside of the inverted vessel D, the tendency to raise a body ofwater inside the float, and force it into the inlet or outlet-passages, is avoided, the float s ow 2 Having thus described my invention,

What is claimed as new, and desired to be secured by Letters Patent, is'

1. The cmmbination' of the cones B and O, forming gradually-enlarging passages for the ingress and egness of the gas to and from the chamber H, substantialiy as set forth. I

2. The hollowoorlieal \l alve F, constructed with apertnres t, an'anged and operating substantially as shown and described.

3. The arrangement of the air-chamber E around the outer periphem of the inverted essel D, as shown and described.

4. The double conical construction ofthe ail-chamher E, substantially purposes set forth" in.
